To date, the study of communicated explanations has been, at best, unsystematic. There has been little recognition that many, if not most, explanations are eventually delivered to a hearer or hearers. These potential audiences constrain the way the explanation is ultimately shaped. Similarly, researchers have devoted themselves to the study of "e;accounts,"e; for the most part without an accompanying interest in the fundamental processes of event comprehension. This volume is devoted to bridging the gap between these two traditions.
